Why Is My AC Unit Leaking Water Inside The House?

If your air conditioner is leaking water inside the house, it usually means water is not draining out the way it should. Instead of going outside through the drain pipe, it is dripping into your room.

Common reasons why your AC unit is leaking water inside include:

1. Blocked drain pipe
2. AC installed in the wrong position
3. Dirty air filter
4. Low AC gas level
5. Broken drain tray
6. Loose or damaged pipe

If your air conditioner is leaking water inside the house, switch it off first. Running it continuously can damage the wall, floor, or wiring near the unit.

What Causes Window AC Water Leakage? (Common Reasons)

understand water leakage from AC indoor unit reasons and what they mean:

Reason for Water Leakage	What Happens	Simple Solution
Blocked drain pipe	Water cannot flow out and starts leaking from the AC.	Clean the drain pipe to remove dirt or blockage.
Wrong AC installation	The AC is not installed at the correct angle, so water flows inside.	Adjust the AC to the correct position.
Dirty air filter	Dust blocks airflow, causing ice to form. When the ice melts, water leaks.	Clean or replace the air filter.
Low refrigerant (AC gas)	The cooling coil freezes and later melts, causing water leakage.	Get the gas checked and refilled by a technician.
Cracked drain tray	The tray cannot hold the water, so it leaks.	Replace the damaged drain tray.
Damaged drain pipe or duct	Water escapes through the damaged pipe instead of draining properly.	Repair or replace the damaged pipe or duct.

Why Is Water Coming From AC Front Side?

Many people notice AC leaking water from front rather than the back or bottom.

This usually happens because of:

1. AC is not installed properly.
2. Dirty or clogged air filter.
3. Dust build-up inside the front panel.
4. Blocked drain hole near the front Air grille

If water is coming from the front side only during cooling mode, it is most likely an airflow or drainage issue, not a major mechanical fault.

People often search for water leaking from split AC indoor unit along with window AC problems because the reasons are similar, but the location is different.

Point	Window AC	Split AC Indoor Unit

Main Cause	Poor installation angle	Blocked drain pipe inside the wall

Repair Time	30–60 minutes	45–90 minutes

Why Does Water Dripping From AC Indoor Unit Happen After Cleaning?

• Water is still left inside the AC after cleaning.
• The air filter was not fitted correctly.
• Air is stuck inside the drain pipe.
